A diagram showing how data flows through an application, system, or network.

A diagram showing how data flows through an application, system, or network.

• A. Database
• B. CSRF
• C. Cryptography
• D. Data-Flow Diagram

Answer: (D)

A data-flow diagram maps how information travels through a system, showing data sources, the processes that transform it, where it is stored, and the paths data takes between those elements. This focus on data movement and transformation across the system is why it’s the best fit for describing “a diagram showing how data flows through an application, system, or network.” A database, by contrast, is just a storage repository and doesn’t illustrate movement or processing. CSRF is a type of web security vulnerability, not a diagram of data movement. Cryptography covers protecting data through encryption, not the flow of data through components.
